No, I don't. If I'm writing in C, and I want to know whether one of my variables is "empty", I have to know what type of variable it is. The code to check whether a string (char x[10]) is "empty" is very different from the code to check whether an array of integers (int x[10]) is "empty". Hell, the meaning of "empty" would have to be defined by the application. Would it mean every element is 0? Or something else? And what if x is a float, or a double? Or a pointer? Or a struct? The same thing happens in bash. It's simply not the kind of language where you have one syntax that works for multiple situations.
